return;
}
//boolean fafa, soso, raerae, gaga, gege;
public void main(Button args[]) {
final boolean fafa = true;
final boolean soso = true;
final boolean raerae = true;
final boolean gaga = true;
final boolean gege = true;
boolean returrn;
OnClickListener list = new OnClickListener() {
#Override
public void onClick(View v) {
if (fafa == true && soso == true && raerae == true && gaga == true && gege == true) {
Toast GetMeToast = Toast.makeText(MainActivity.this, "Open all buttons", Toast.LENGTH_SHORT);
GetMeToast.show();
}
}
};
}}
I tried to run the code above but was jammed once i clicked the button.
I am new to java. Required some assistance, what i need is that by clicking all the 5 buttons then the toast will appear.
I have tried many way it does not work. I think by creating a Boolean and if method can help me with this.
